Traumatic cardiac arrest
Background
- Classically thought to death invariably
- However, recent data suggests that survival from traumatic cardiac arrest is similar to that of medical causes of cardiac arrest[1]
- One military study demonstrated 24% survival of patients who underwent resuscitation after traumatic arrest[2]
Clinical Features
- Initial rhythm usually PEA
Differential Diagnosis
- Differential diagnosis should be thought of in terms of reversible causes
- Massive hemorrhage and hypovolemia
- Tension pneumothorax
- Hemothorax
- [Cardiac tamponade]]
- Hypoxia and airway compromise
- Pelvic trauma
- Hemodynamically compromising long bone fractures
Evaluation
- Pre-operation labs
- Base excess, ABG/VBG, lactate
- Type and cross
- CXR
- Pelvic XR
- eFAST
Management
- Large bore PIV or central line access with blood products, massive transfusion
- Establishing resuscitation airway
- Bilateral thoracostomy
- Emergency thoracotomy
- REBOA catherization and balloon inflation
- Long bone fracture reduction, if there is suspicion of significant enough hemorrhage
- Pelvic binding
- Surgical stabilization
- Standard ACLS and BLS may delay critical interventions
- No definitive animal or human evidence to support external chest compressions in traumatic cardiac arrest[3]
- No evidence to support IV epinephrine in traumatic arrest, with the exception of neurogenic shock
Disposition
- Emergency surgery
